This paper presents a study of permanent magnet machines for automotive applications, comparing different slot, pole and phase number combinations in terms of torque and power output and NVH performance under constraint of the same active volume. FEM simulations are used to estimate electromagnetic performance and an analytical model to evaluate noise emissions for each configuration. In this analysis, a novel two-phase machine with mildly overlapped windings emerges as the best combination between NVH and electromagnetic performance, at the expense of a 4-leg power converter instead of a standard 3-phase 2-level inverter.

Abstract
This paper presents a study of permanent magnet machines for automotive applications, comparing different slot, pole and phase number combinations in terms of torque and power output and NVH performance under constraint of the same active volume. FEM simulations are used to estimate electromagnetic performance and an analytical model to evaluate noise emissions for each configuration. In this analysis, a novel two-phase machine with mildly overlapped windings emerges as the best combination between NVH and electromagnetic performance, at the expense of a 4-leg power converter instead of a standard 3-phase 2-level inverter.File | Dimensione | Formato | |
